IMPROVEMENT IN WATER-ELEVATO RS.

Specification forming part of Letters Patent No. 36,07l, dated August 5, 1862.

To a/ZZ whom, it may concern.-

Be it known that I, JACOB D. GHEIsTIE, of Hackensack, in the county of Bergen and State of New Jersey, have invented a new and Improved Windlass, designed more especially for well-curbs; and I do hereby declare that the following is a full, clear, and exact de-` scription of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side sectional view of my invention, taken in the line x Iv, Fig. 2. Fig. 2 is a section of the same, taken in the line y y, Fig. 1. Fig. 3 is a section of the same,taken in theline y y', Fig.'2. Fig. 4 is a section of the same, taken in the line z z, Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in Va novel arrangement of parts, as hereinafter fully shown and described, whereby articles may beraised to the desired height and lowered as desired at any time at a quick or slow pace, as circum stances may require.

The object of the invention is to obtain a windlass which willbe under the complete control of the operator, both as regards the raising and lowering of articles by them, and by a very simple arrangement of means.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a framing which may be constructed in any proper way, and B is a hollow or tubular shaft which is fitted in bearings a a on the frame A and allowed to turn freely thereon. On the shaft B adrum or pulley,0, is secured, to which the article'to be raised is attached by a cord or chain, as usual.

At one end of the tubular shaft B there is a ratchet, D, having an annular ange, Fi, projecting at right angles from its outer surface, as shown clearly in Fig. 2. The ratchet D and flange E are permanently attached to the tubular shaft B, and within the shaft B there is placed a fixed shaft, F, secured at one end by a nut, b. The shaft F has a ratchet, G, secured permanently to one end of it, and also a collar, H, the latter being attached to the ratchet G.

On the collar H there is placed loosely a cylindrical box or drum, I, into which the flange E of the ratchet D ts loosely, the inner side of the box or drum I being open. The box or which a segmentslide, L, istted. This segment-slide serves as a brake and is allowed to work in and out in the drum I under the action of the back end of the pawl J. The front end of the pawl J is provided with a lip, f, which engages with the teeth of the ratchet D when the box or drum I is turned from leftvto right, as indicated by the arrow l.

M is a circular disk to which a crank, N, is attached. This disk M, like the drum I, is fitted loosely on the collar H of the ratchet G and at the inner side of ratchet G, as shown clearly in Fig. 2. The disk M has twolips, g, at its inner side, between which the front end of the pawl J tits.

To the outer side of the box or drum I there is attached a pin, O, which projects horizantally through a slot, P, in the disk M. The form of this slot is shown in Fig. 1. On this pin there is fitted avpawl, Q, which engages with the ratchet G, and is kept in contact therewith by a spring, R.

The operation is as follows: Vhen the disk M is turned in the direction indicated by arrow l, the front end of the pawl J engages with the ratchet D, and the tubular shaft B and drum or pulley G will be turned and the article elevated in consequence of the rope or chain to which it is attached being wound upon the drum or pulley C. In order to lower the article,the disk M is turned in the reverse direction a triling distance, so that the lips g will throw the front end of the pawl J out from the ratchet D and the back end of the pawl be pressed against the slide or brake L, and the latter pressed against the flange E of the ratchet D, so as to regulate the descent of the article as may be required. The disk M is allowed to be turned back a distance equal to the length of the slot l?, through which the pin O passes, and the pawl Q, which is engaged with the ratchet G, keeps the box or drum I and slide or brake L stationary during the backward movement of disk M. Thus by this simple arrangement it will be seen that the windlass s placed under the complete control of the operator, the article .being capable of being raised and lowered to any desired point, fast or slow, and held or retained at any point required.

The invention is admirably adapted for wells in raising water by means of buckets, as the empty buckets may be lowered rapidly at rst and the speed checked before they touch the water, so as not to be injured by violent contact therewith.

I do not claim, separately, any of the parts; but

I do claim as new and desire to secu re by Letters Patent#- The hollow or tubular shaft B, with the ratchet D and ange E attached, in combination with the stationary or fixed shaft F, with ratchet G attached, and the box or drum I, with pawl J secured to it, andthe slide or brake L, fitted in drum I, the above parts being used with the disk M and all arranged for joint operation, as and for the purpose herein set forth.

JACOB D. CHRISTIE.
